Indian troops are defending every inch of the border with China and not even a single inch of land has been taken over by the neighbouring country in recent years, Ladakh Lt Governor Brig (Retd) B D Mishra said on Thursday.

He said infrastructure development is taking place at a rapid pace across Ladakh with roads, helipads, airfields, tunnels and bridges being built, and India will catch up with China in that regard within next four-five years.

Brig Mishra (Retd) was in Jammu in connection with a three-day north-tech symposium which concluded at IIT Jammu on Wednesday.
